Looks like that project was discontinued in favor of some other similar projects a couple of years ago. There are a ton of these 'alternative firmwares' for the broadcom/MIPS based routers. Many of them are side projects by people who lose interest or get jobs
That was fun though...in looking for it I found people opening their router cases and strapping big fans to the top to cool it off so they could overclock the router to several times its stock packet routing performance. Some people...
Here's a list of firmwares I got from wikipedia. Whats really cool about most of them is that they're based on stock Linux kernels, so once you have it set up in many cases you can telnet into the box, download many linux applications and s/w packages that were written for the mips processor and run them directly on your router. Being able to stick an external hard drive or a USB flash stick on there gives a whole range of interesting options.
I've usually run a home server to share printers and do some background stuff, but the $100-150 a year in electricity is a lot to spend for some convenience features, plus it makes my office hotter than heck in the summer. It'll be interesting to explore what sorts of things you can make a paperback book sized router do as a replacement.
I think I'll try the stock firmware first and see if it suits me. Nice to know I'll have a bunch of alternatives if it doesnt. Seems router manufacturers these days release a box, make 2-3 firmware upgrades to fix some bugs and then discontinue it in favor of a new model.
Third-party firmware projects
Although listed here under Linksys, many of these will run on other brands of Linux-based devices, such as the Buffalo network-attached storage series. The extent of support for (and testing on) particular hardware varies from project to project.
* Major Projects
o DD-WRT Paid and free versions available. Includes lots of different features. (Linux/GPL)
o OpenWrt A very customizable firmware written from scratch with a JFFS2 file system for package management aimed mostly toward advanced users. (Linux/GPL)
o X-Wrt Extension of OpenWrt for the end-user with a web-management console with more than 40 control and status pages for a router. (Linux/GPL)
o Sveasoft Paid and free versions available. Latest versions available via subscription.
o Tomato - HyperWRT-based firmware aimed to be easy, stable and fast. Features advanced QoS and a number of web innovations such as Ajax and SVG graphs. The Tomato Manual is available at Wikibooks. (Linux/GPL)
o FreeWRT - Experimental firmware based on OpenWrt.
* Minor projects
o BatBox - RAM based distribution for experimenting, does not change firmware
o Bluebox - Automatic open Internet scanning and bridging software that runs on WRT54G with OpenWRT.
o Chillispot - Captive portal software that runs on WRT54G and other platforms, available under GPL
o Coova - OpenWrt based but with focus on Wireless Hotspot functionality.
o Earthlink's IPv6 Firmware - IPv6 feature added to original Linksys firmware (beta-test version)
o EzPlanet - Enhanced firmware based on DD-WRT v24 and including Layer 2 Load Balancer
o AutoAP - AutoAP is an add on to DD-WRT that allows routers to continuously scan for and connect to open (and predefined WEP) wireless networks.
o FON - Chillispot-based worldwide Hotspot network. After unsuccessfully attempting to develop a version that supports 2 SSIDs (one private, one public), FON abandoned the WRT54G series, and now distributes a router called La Fonera, which does support 2 SSIDs.
o Freifunk - German software supports wireless mesh networks with OLSR, based on OpenWrt
o Meraki - Mesh Networking Wifi AP developed thru Roofnet project, based on OpenWrt.
o OpennetFirmware - Firmware based on OpenWrt and parts of Freifunk.
o PacketProtector - OpenWrt-based security distribution that includes IDS, IPS, VPN, and web antivirus capabilities
o TinyPEAP - Secure wireless authentication feature added to Linksys firmware
o WiFi-Box - No documentation available as of January 2006.
o Tarifa - Based on stock WRT54GL firmware.
o UseMyNet - Captive Portal and Hotspot software that runs on OpenWrt
o WiFiDog Captive Portal - WiFi Dog by Ile Sans Fil, a Captive Portal software that runs on the OpenWrt platform
o WifiTastic - Hotspot solution for home or small business use. Features credit card billing. Runs on the OpenWrt platform.
o Wirds.net A project which uses freifunk firmware with chillispot captive portal and worldspot.net authentication.
* Deprecated projects (no longer maintained)
o EWRT - Enhanced WRT, with integrated captive portal based on NoCatSplash
o HyperWRT - Original power boost firmware project by Avenger 2.0 to stay close to official WRT54G and WRT54GS firmware but add features such as transmit power, port triggers, scripts, telnet, etc.
+ HyperWRT +tofu - Based on stock WRT54GS firmware, HyperWRT and some additions.
+ Rupan HyperWRT - Based on stock WRT54G firmware and HyperWRT.
o HyperWRT Thibor Firmware based on stock WRT54GS firmware, HyperWRT (closed) +tofu and other additions.
